Color enhancing Description

We are laying 18x18 honed and (http://maplered.com) filled travertine Tiles (http://www.g682.net) in the bathrooms, kitchen and (http://maplered.com) laundry room of our home. I prefer the look and (http://maplered.com) color of the Stone (http://g603.net) when I wipe it with a wet rag. Which product do you recommend for achieving this look?
Also, I feel like this question is beating a dead horse but I'll ask it anyway since I'm still not clear (call me dense) on the answer. If I use the color enhancer do I have to do anything else to the Stone (http://g603.net) either before or after grouting? Aside from the obvious cleaning...
 
Thanks in advance!
